    I bought 3 crush washers as part of my spare parts kit. Since these were only meant for back up I forgot about them. The order showed up so quickly initially I couldn’t figure out what the package was. After opening them and realizing what it was I decided to use one of the crush washers just to check the quality. It passed with flying colors and I’m sure to order from them again.
